摘要： An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer after fully recording a recordable area of a first data storage layer. Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.

摘要： A recording layer and a flux adjustment layer have different magnetic polarities so that their magnetizations are countervailed at room temperature, with the result that a weakened leakage magnetic flux is released therefrom. A reproducing layer, a reproducing assist layer and an in-plane magnetization layer exhibit in-plane magnetization at room temperature. In a first temperature area having a temperature not more than the critical temperature of the reproducing layer, the reproducing layer 1 exhibits in-plane magnetization so that magnetization of a recording magnetic domain is not copied to the reproducing layer. In contrast, a second temperature area having a temperature rise between the critical temperature and the Curie temperature of the reproducing layer, the flux adjustment layer and the in-plane magnetization layer have reached their Curie temperatures and lost their magnetization; thus, a leakage magnetic flux generated by the magnetization of the recording magnetic domain is copied to the reproducing assist layer that is in a perpendicular magnetization state, and further copied to the reproducing layer. Moreover, in a third temperature area having a temperature rise exceeding the Curie temperature of the reproducing layer, the reproducing layer has lost its magnetization.
摘要翻译：记录层和磁通调节层具有不同的磁极性，使得它们的磁化在室温下抵消，结果是从其中释放出弱化的漏磁通。再现层，再现辅助层和平面内磁化层在室温下表现出平面内的磁化强度。在温度不超过再生层的临界温度的第一温度区域中，再现层1表现出平面内的磁化，使得记录磁畴的磁化不被复制到再现层。相反，具有临界温度和再生层的居里温度之间的温度上升的第二温度区域，通量调节层和面内磁化层已经达到居里温度并失去其磁化强度; 因此，由记录磁畴的磁化产生的泄漏磁通被复制到处于垂直磁化状态的再现辅助层，并进一步复制到再现层。此外，在温度升高超过再现层的居里温度的第三温度区域中，再现层已经失去其磁化。
